RQ1: Existence and Generality. Do there exist common features or artifacts shared across different diffusion models?

RQ2: Uniqueness and Visualization. Does each diffusion model enjoy its unique fingerprint [1]}, [2]}, [3]} that differentiates itself from other diffusion models? And how to expose these unique fingerprints?

RQ3: Prompt Analysis. Which kind of semantics and structures of prompts can generate more real\fake images?
